Clinically Validated Sleep Tracking — Without Wearing a Thing

Real-time heart rate, breathing patterns, and sleep stages — validated in clinical studies. No wearable. No camera. No subscription.

Why Parents and Sleep-Conscious Adults Choose OZI

OZI delivers the sleep data accuracy of top-grade sleep tracking watches and rings — without anything on your body. And unlike every other sleep tracker built for individual use only, OZI lets parents monitor their children’s sleep in real time from their phone. No camera. Nothing on the child. Guardian Mode also alerts you the moment something seems off.

PREMIUM-LEVEL ACCURACY

OZI delivers 98% correlation and matches top-tier wearable sleep trackers (watches and rings) across core sleep accuracy metrics in independent studies. It is also 45% more accurate than popular fitness bands and smartphone apps, with precision detection for exact bed entry, sleep onset, and micro-awakenings. By capturing the details many devices miss, OZI provides a more complete and dependable picture of your sleep.

Fall Asleep Faster. Wake Up Feeling Human.

Soundscape

Drift off with adaptive sleep sounds — white noise, rain, ocean waves, and more — automatically turned off the moment OZI detects you’ve fallen asleep. No need to set a timer. OZI handles it.

Smart Alarm

Set a wake-up window and OZI does the rest. It monitors your sleep stages in real time and wakes you at the lightest point within that window — so you emerge from sleep naturally, not dragged out of deep sleep by a jarring alarm. Choose a 5, 10, 15, or 30-minute window. Works every night, automatically.

See What’s Happening Right Now — Get Notified When It Matters

Real-time

Unlike Withings Sleep Analyzer and most non-wearable trackers that only show data after the night ends, OZI delivers live heart rate, breathing rate, and sleep stage data throughout the night. Open the app at any time and see exactly what’s happening.

Guardian Mode

Configure exactly what triggers an alert — low heart rate, high heart rate, bed exit timeout, breathing changes — and how you receive it: push notification or email. Set monitoring windows so you only get alerted during hours that matter. Guardian Mode is designed for parents watching over children, but works for anyone who needs nighttime peace of mind.

Top-Tier Accuracy. No Subscription. Total Peace of Mind.

A smarter way to track sleep — for you and the people you love.
